Kunitskaya (10-3) is a former Invicta FC bantamweight champion, and makes her debut at 145 pounds. Kunitskaya had been scheduled to make her Octagon debut with Leah Letson at UFC on Fox 28 on Feb. 24. She is heading into the contest with a 2-2-1 record in her last five fights.

Originally, Max Holloway and Frankie Edgar were set to headline the show vying for the featherweight title. The fight was canceled last week, as Holloway suffered an ankle injury. Edgar (22-5-1) will remain on the card and face rising prospect Brian Ortega (13-0, 1 NC) in the co-main event. The winner is expected to get the next crack at Holloway.

After Holloway-Edgar fell through, the UFC attempted to book a rematch between T.J. Dillashaw and Cody Garbrandt for the bantamweight title. Garbrandt agreed to the contest, but Dillashaw refused to take it on short notice. Sources told SN that if a championship bout couldn't be made, then either the card would have been shifted to Fox Sports 1 or canceled.
